Software I work on in my free time

Apps

Most of the time I’m working on K-9 Mail. But occasionally I find the time to create a small app.

K-9 Mail

This is what got me into Android development. K-9 Mail is a powerful email client for Android that is currently used by more than 2 million people. And it’s probably one of the oldest open source Android apps.

To date over 140 people have contributed to the app. But there is still a lot of work to be done. And we welcome every helping hand. Head over to the project page on GitHub to learn more.

Attach Contact

This app allows you to attach contacts to your emails just like any other file. Android’s Contacts app itself only supports this functionality via the Share action. But that can’t be used e.g. when replying to an email.

SafeContentResolver

EmailIntentBuilder

EmailIntentBuilder is an Android library for the creation of a android.intent.action.SENDTO Intent with a mailto: URI. Apps can use this Intent to tell the user’s email app to compose a new message with some fields prepopulated.

Example usage:

EmailIntentBuilder.from(activity).to("alice@example.org").cc("bob@example.org").bcc("charles@example.org").subject("Message from an app").body("Some text here").start();
